I agree with comments, a well handled engine failure, and probably good advertising for the machine. Everyone got out and it handled the auto into the water pretty well.
Good on them. For those interested, the specs are pretty impressive. Similar to a 66 and way better than a 206.
Glad they are OK. The world needs motivated people like these guys.

PS - it was a photo flight, not testing, they have already flown over 200 hours in the type.
